No doubt about it, it'd have plenty of torque. I work at a glass factory and they tow loads in excess of 25 tons with a 48 volt electric forklift. But, along with the problem with the spare battery, you'd also have to consider trying to work on it should you have problems with it. I used to be a forklift mechanic and let me tell you, they can be a BEAR to deal with!! The idea sounds good, but I personally don't think they'll fly.
